Alexander Disease (GFAP) Gene Analysis Test
Alexander disease (GFAP) gene analysis Price
Brief Details
What is the Alexander Disease (GFAP) Gene Analysis Test?
The Alexander Disease (GFAP) Gene Analysis Test is a genetic blood test used to diagnose Alexander disease, a rare disorder of the central nervous system characterised by progressive damage to the white matter of the brain.
The condition is caused by mutations in the GFAP gene, which plays a key role in maintaining normal function of astrocytes in the brain. This test uses next generation sequencing technology to identify disease causing genetic changes, helping confirm diagnosis and support long term care planning. The test requires a blood sample collected in an EDTA tube.
What Does the Alexander Disease (GFAP) Gene Analysis Test Measure?
This genetic test looks for disease causing changes in the GFAP gene:
- Detects pathogenic variants responsible for Alexander disease
- Helps confirm the diagnosis of leukodystrophy
- Supports early diagnosis in infants, children, or adults
- Aids genetic counselling and family screening
- Assists clinicians in prognosis assessment and care planning

Interpreting Alexander Disease (GFAP) Gene Analysis Test Results
What Your Alexander Disease (GFAP) Gene Analysis Results May Indicate
| Parameter | Expected Finding | Pathogenic Variant Detected May Indicate | No Variant Detected May Indicate |
|---|---|---|---|
| GFAP gene | No disease causing variant detected | Confirmed Alexander disease | Symptoms may be due to other leukodystrophies or variants not detected by this analysis |
Understanding Abnormal Alexander Disease (GFAP) Gene Analysis Results
| Finding | What It May Indicate |
|---|---|
| Pathogenic GFAP variant | Alexander disease with associated neurological progression |
| No pathogenic variant | Alternative neurodegenerative or metabolic disorder |
How Should You Prepare for an Alexander Disease (GFAP) Gene Analysis Test?
This genetic test requires minimal preparation from your side:
- No fasting required: You can eat and drink normally before sample collection
- Normal hydration: Maintain your usual fluid intake
- Medication disclosure: Inform your doctor about any medicines or supplements
- Share clinical history: Provide relevant neurological and family history
- Consent and documentation: Ensure the test requisition form and clinical details are completed
How Is an Alexander Disease (GFAP) Gene Analysis Test Done? (Step-by-Step Procedure)
The test is performed using a standard blood collection process:
- Preparation: A tourniquet is tied around your arm to make veins more visible
- Cleaning: The puncture site is cleaned with antiseptic
- Sample Collection: A sterile needle is used to draw about 3 to 5 ml of blood into an EDTA vacutainer
- Completion: The needle is removed, and a bandage is applied
- Processing: The sample undergoes next generation sequencing to analyse the GFAP gene
Conditions That May Affect Alexander Disease (GFAP) Gene Analysis Test Accuracy
Certain patient related factors may influence test interpretation:
- Recent blood transfusion, which may affect genetic analysis
- Incomplete or inaccurate clinical history
- Presence of mosaic genetic changes requiring clinical correlation
